The patented Aquapod™ is a unique containment system for marine aquaculture, suited for rough open ocean conditions and a diversity of species. The Aquapod is constructed of individual triangle net panels fastened together in a spheroid shape. Most Aquapod net panels are made of reinforced high density polyethylene with 80% recycled content and covered with coated galvanized steel wire mesh netting. Individual net panels or groups of panels are modified to accommodate other functions, such as access, feeding, fish transfer, grading, and harvesting. The Aquapod functions as a secure containment system for finfish while submerged or partially surfaced.
